What happens to the voltage in a series circuit if one component fails?

In a series circuit, all components are connected end-to-end, forming a single path for current to flow. If one component fails—like a resistor or a light bulb—the circuit becomes open. This means that there is a break in the path, preventing the current from flowing through the entire circuit. As a result, all components downstream of the failure will not receive any voltage, and the whole circuit effectively stops working. This phenomenon illustrates the critical nature of each component in a series setup; the failure of one impacts the entire system. The current ceases, and consequently, the voltage across any remaining components becomes zero since there is no complete loop for current to circulate.
